Follow instructions given by Prophet Muhammad(PBUH). Wash away any blood from yourself and resume prayer after your period has passed .

This hadith speaks of the importance of cleanliness and prayer in Islam. It is narrated that a woman asked the Prophet Muhammad (PBUH) if she should stop praying due to her not becoming pure, and he replied that it was not menstruation but rather a vein. He then instructed her on how to proceed when her period comes; she must stop praying until the same amount of time as her regular period has passed before washing away any blood from herself and then resuming prayer. This hadith teaches us that cleanliness is important for prayer in Islam, as well as emphasizing the importance of prayer itself.
